Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm monitoring device which outputs an alarm message to an alarm screen on a CRT display device when an abnormality occurs in a plant to notify an operator of the abnormal condition.

[0002]

2. Description of the Related Art For example, alarm monitoring in a large-scale plant such as a thermal power plant displays an alarm screen on a CRT display device and outputs an alarm message on the alarm screen to notify an operator of the abnormal condition. I am trying to notify you. In this case, when a plurality of alarms occur simultaneously, the alarm messages are output to the CRT display in the order in which the alarms occurred. If the message does not fit on one screen, the old alarm messages are sequentially sent to the back page. for that reason,
If the most urgent message was an early warning, the operator would have to return to backpage.

In recent years, alarm messages have been sorted according to the ranks of the systems by sorting the alarm messages according to the systems constituting the plant and the importance (rank) of the alarms. That is, since the warning message is output for each system in the order of the rank, it is improved so that it is possible to immediately determine which system and which level of the alarm is being output.

FIG. 7 is a configuration diagram of such a conventional alarm monitoring device. The plant state signal is first input to the alarm processing unit 2 via the process input unit 1. The alarm processing unit 2 performs an abnormality determination of the input plant state signal, and creates an alarm message when the plant state signal is abnormal. This warning message is output to the display output processing unit 3. In this case, the warning message is sent to the sort condition processing unit 1
4 and output to the display output processing unit 3. That is, the warning message is output for each system in the order of the rank.

[0005] The display output processing unit 3 displays the alarm message sent from the alarm processing unit 2 on the CRT display device 4 and the large screen 11. As described above, in the alarm monitoring device in which the large screen 11 is installed, conventionally, the same display content as the CRT display device 4 is displayed on the large screen 11. The mouse 7 and the trackball 8 are input devices for interacting with the alarm monitoring device through a screen displayed on the CRT display device 4.

[0006]

However, in the conventional alarm monitoring device, since the alarm message is only displayed and output to the CRT display device 4 for each rank for each system, it is an alarm that is determined to be particularly important. Even if the system is different, it will not be displayed. When monitoring an alarm, the operator may need to immediately respond to the alarm message in response to the alarm, and in order to respond to it, it is necessary to know the most urgent alarm. Take precedence.

That is, in the conventional alarm monitoring device, although it is desired to monitor alarms determined to be particularly important without distinguishing the systems, they cannot be displayed together on the CRT display device 4.

Further, since the screen displayed on the CRT display device 4 is displayed on the large screen 11 as it is, it is all necessary information for the operator, but it is necessary for all the operators including the shift supervisor. Sometimes had too much information.

In FIG. 1, a search sort condition input unit 5
When a plurality of warning messages are displayed on the warning screen of the CRT display device 4, the warning message to be displayed by the operator is selected. That is, the operator uses the mouse 7 or the trackball 8 to set search / sort conditions for the alarm message.

Further, the search / sort processing section 6 determines whether or not search / sort conditions are set for the alarm message created by the alarm processing section 2, and if the search / sort conditions are set, And outputs a command to the display output processing unit 3 to display a warning message on the CRT display device 4 according to the search / sort condition.

That is, when a driver wants information related to a certain alarm with respect to a plurality of alarm messages, the operator inputs necessary conditions to the search / sort condition input unit 5 with the mouse 7 or the trackball 8. Thereby, the operator can search for desired information (important alarm).

FIG. 2 is an explanatory diagram of a search sort condition.
FIG. 2A shows device-specific conditions for designating component devices of a plant. For example, in the case of a thermal power plant, there are a boiler, a turbine, and a generator as main engines, and other common equipment. Therefore, equipment-specific conditions are provided as conditions for selecting and specifying these equipment. .

FIG. 2 (b) shows conditions for each degree of importance indicating the degree of failure. The degree of failure includes a major failure, a minor failure, a special alarm, and the like, and these are provided as conditions according to importance. FIG. 2C shows the conditions for each control device.
(Controller for turbine), sequencer, ABC (automatic boiler controller) and the like.

FIG. 2 (d) shows conditions for each system, in which systems such as a main steam system, a bleed steam system, a water supply system, and a seawater system are selected. FIG. 2 (e) shows conditions for each auxiliary machine. Select auxiliary equipment such as pumps, valves, condensers, feed water heaters, and deaerators. Hereinafter, similarly, FIG. 2 (f) shows the conditions for each individual pump such as a boiler feed pump, a circulating water pump, a vacuum bomb, a main oil pump, etc., and FIG. 2 (g) shows a main steam stop valve, a control valve. , Reheat steam stop valve, etc., and FIG. 2 (h) shows the condition for each flicker item on the alarm screen.

The operator selects these search sort conditions as appropriate. That is, the important alert is selected without particularly selecting unnecessary selection conditions. Thereby, the search sort processing unit 6
The warning message is searched and sorted by the CRT display device 4.
Output to That is, when many alarms are generated and many alarm messages are displayed on the CRT display device 4,
In such a case, it is difficult to determine the important alarm. In such a case, the operator selects the condition considered to be the most important corresponding to the plant operating state at that time on the various condition shown in FIG. 2 on the selection screen. This allows only important warning messages to be displayed. If these search sort conditions are set in advance, alarm messages that match the search sort conditions are automatically sorted and displayed on the CRT display device 4.

As described above, according to the first embodiment, the operator can quickly determine the important alarm,
The corresponding operation can be performed directly. That is, since the search sorting condition can be set arbitrarily, the operator can immediately search for and display an alarm message to be displayed on the CRT display device 4. Thereby, the warning message having urgency can be automatically known to the operator, the burden on the operator can be reduced, and a quick response operation can be performed.

Next, a second embodiment of the present invention will be described. FIG. 3 is a configuration diagram of the alarm monitoring device according to the second embodiment of the present invention.

In FIG. 3, in the condition setting section 9, alarm search sort conditions are set in advance according to the plant operation state. Here, as the plant operation state, for example, there are operation states such as a boiler start-up preparation stage, a boiler ignition stage, a stage of increasing and raising the temperature of steam, a turbine ventilation stage, and the like. It is a thing.

That is, the search / sort conditions set by the operator are usually patterned in the operating state of the plant in many cases. For example, when the temperature is increased from the boiler ignition before the turbine is started, the equipment shown in FIG. It is considered that a boiler relationship is often selected under different conditions, and an ABC (automatic boiler control device) relationship is often selected under control device-specific conditions. Therefore, the operator does not individually select the search sorting conditions according to the plant operation state every time, but collectively stores the search sort conditions according to the plant operation state in the condition setting unit 9 in advance. . Thus, the operator can set the search sorting condition of the alarm corresponding to the operation state of the plant with one touch.

According to the second embodiment, an important warning message can be displayed on the CRT display device without the operator having to set many search / sort conditions, and quick response operation is possible. Becomes
